Throw System.Data.Entity.Core.ProviderIncompatibleException when "Enable migrations"

billzhuang opened this issue 3 years ago · 4 comments

sample repo here: https://github.com/myspyx/ef6play

pretty simple code from
https://www.npgsql.org/ef6/index.html
and https://docs.microsoft.com/en-us/ef/ef6/modeling/code-first/workflows/new-database

the code works well at first time, create databse automaticly for me, but if I change anything in the model, and try to "Enable migrations", it will throw exception of System.Data.Entity.Core.ProviderIncompatibleException.

Any idea? I try different Postgres verision, no lucky.
Run Postgres in docker for test with below
docker run --name some-postgres -p 5432:5432 -e POSTGRES_PASSWORD=postgres -d postgres:11

@billzhuang note that this provider is archived and no longer being actively maintained.

Answer 2 · 2021-11-14T15:17:53.000Z

@roji yep, since EF6 also live in maintain Mode, I suppose this repo should work with EF6 together happy.:)

Any idea from your experience why this exception happened in enable migration phase?

Appreciated.

Answer 3 · 2021-11-15T16:12:49.000Z

add assembly binding in app.config
<dependentAssembly> <assemblyIdentity name="System.Threading.Tasks.Extensions" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-4.2.0.1" newVersion="4.2.0.1" /> </dependentAssembly>
There is an assembly version conflict.

Hi @icewindq , amazing! You saved my time. After add the binding redirect, works like a charm.
